From 7d5f190a6c3dca378f10ef7ef942e398dab786f4 Mon Sep 17 00:00:00 2001 From: Vaughn Friesen Date: Thu, 11 Jun 2026 19:13:41 +0800 Subject: [PATCH 1/2] docs: fix godoc rendering and restore full AGENTS.md mirror - Restore AGENTS.md as a full, agent-neutral mirror of CLAUDE.md with cross-references so the two files stay in sync - Replace the stale backward-compatibility rule with the version 0 policy and a docs-update checklist naming the real doc surfaces - Rejoin batch/doc.go's package comment so the batching priority rules render on pkg.go.dev again, and correct the batch-timing sentence (windows open at dispatch, not when the previous batch finishes) - Remove the duplicate package comment in batch/config.go - Document Config.Get accurately: Batch normalizes values via fixConfig; a zero MaxItems/MaxTime means no maximum applies - Indent dash lists in batch, processor, and source docs so godoc renders them as lists instead of run-on paragraphs - Drop processor/doc.go's blanket context-cancellation claim (Transform, Filter, and Error do not check ctx) Co-Authored-By: Claude Fable 5 --- AGENTS.md | 14 +++++++------- CLAUDE.md | 14 +++++++------- batch/config.go | 16 ++++++++-------- batch/doc.go | 12 +++++++----- processor/doc.go | 14 +++++++------- source/doc.go | 6 +++--- 6 files changed, 39 insertions(+), 37 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index 373b77c..3d02b1e 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -1,6 +1,6 @@ -# ChatGPT Instructions +# Agent Instructions -This file contains instructions and guidelines for ChatGPT when working with this project. +This file contains instructions and guidelines for AI coding agents when working with this project.
